The invention relates to printing mocha-- nisms for cash registers, with whichthe impression of the set type wheels on a record strip and a check is effected by means of one and the same platen and, in particular, the printing of the check is capable of being effected selectively by means of difl'erent adjusting means which are independent of one another.

The essence ofmy invention resides in the fact that the actuation of the platen to print the check and the record strip is eifectedby actuating elements rigidly connected to one 1 another and adapted to be changed over,

while the actuation of the check cutting and perforating mechanism, the record strip feed mechanism and the adjusting device for the impression of the date are effected by means which work unchangedly on every operation of-the machine. p

In comparison with known'arrangements of the character stated, in which each individual device'of the complete printing mechanism is operated by an independently controlled actuating means, my novel mode of operating the individual devices offers the I advantage of greater simplicity and clearness of arrangement. The invention Wlll now be described in detail. with reference to the accompanying drawings which form part of this specification and illustrate, by way of example one embodiment .of the subject-matter of my invention, a printing mechanism issuing a stub check.

In these drawings:

eferring now to Fig. 1 of these drawings,

' 1 denotes the record strip fed from a supply spool 2 and led over a hub 3.and a roller laten 4 to the stora e spool 5. 6- denotes a c eck 1 paper strip led mm a supply spool 7 to the ceding and cutting mechanism by a guide 8. An'i'mpression is effected on said record strip on each'operation' of the machine.

The feeding mechanism 9, Fig. 1, for. the record strip, which is of known construction, is operated by a rod '10 linked to a four- I armed lever. 12 loosely rotatable on a fixed ona shaft 20, and to a link22. Pin 19 car- 1 was a spring pawl 2.3 which cooperates with a ratchet wheel 26 fixed, to the, roll 24., Fig.

1, which inks and feeds the ink ribbon -25.

Link 22, Figs. 6 and 1, is pivotally connected. to anarm 28' rigid on a shaft 27. On a second arm 29 rigid, on shaft 27 Fig. 1, islinked a springpawl 30 which co-operates with a ratchet wheel 31 implarting feed motion to the type wheels for t e consecutive number.

A spring-actuated counter'pawl 33 loose on a shaft 32, Fig. 1, prevents the ratchetfwheel 31 from'turning backward. a

Upon the driveshaft-15 rotating clockwise Fig. 6, the lever 12 has imparted to it,

at the beginning of each operation of the machine, a single to and'fro rocking motion starting clockwise, b means of the cam disks 16, 17, thus feeding the record strip 1-, ink ribbon 25 and number ratchet wheel 31.

On a. shaft 36 mounted in the side walls 34,35, Fig. 3, of the frame are arranged six type wheels 37 for the amounts, four.

type wheelsB-S forv the consecutive number and fourtype wheels 39 for 'thedate.

the types of said wheels.

The amount type wheels 37 are connected in a well-known manner by nested tubes 40, 41 and intermediate pinions 42, 43 with the differential mechanism of the machine. T he units wheel of the type wheels 38 for the con secutive number has fixed to it the abovementioned ratchet wheel 31 feeding said t e wheels 38. Shaft 36 has a recess 44, igs. 3 and 1, located in the range of type wheels 38 and causing them, in a well-known manner, to return to zero, when shaft 36'is The date wheels 39 are mounted on a sleeve '48, Figs. 5 and 3,the shell surface of which is normally concentric to shaft 36 While its .bore is-eccentric thereto, and which is connected to a pitman 54 by an arm 49, Fig.5, rigid on it, a link 50, an arm 51, a shaft 52 and an arm 53 rigid on the latter. Pitman 54 embraces by its bifurcated end the drive shaft 15 and engages by a roll 55a curved groove 56 of cam disk 17. The space left between sleeve 48 and shaft '36 is occupied by another eccentrically bored sleeve 57 rigid on the frame wall 34, Fig. 3, and thus prevented both from rocking wlth sleeve 48 and rotatiingpwith shaft 36. 1

he types of the date wheels 39, when set into the printing path opposite to roll 4, Fig. 1, are'normally kept at the same distance away from said roll as the settypes of the other type wheels, so that, upon the roll 4 executing a printing motion, also an impres- .sion of the set date is produced. Upon drive shaft 15 rotating, pitman 54, Fig. 5, however,

has imparted to itaane single rocking motion towards the right, thus rocking the eccena tric sleevef48 anti-clockwise and withdrawing the set types from roll 4 to such anextent that an impression of the date onto. the record strip does not take place.

The cuttin mechanism comprises a cylindrical kni e 58, Figs. 9,10, 1, which is mounted for rotary motion in a sleeve 59 and connected by an arm 60, Fig. 7, a link 61,'a double lever 63 loose on a fixed shaft 62, and a rod 64 to an-oscillating lever 65, which co-operates by rolls 66, 67 with two cam disks 68, 69 rigidon drive shaft 15; The knife 58 has a slot for the passage of the check paper. Its right-hand upper edge 70, Fig. 10, forms the cutting edge and 00-01)- erates with the companion knife 71 fixed on sleeve 59. The lower edge opposite to edge 7O, of knife 58, forms a perforating punch 72. The cam disks 68, 69 are of a configura t on such as to cause the knife 58 to turn once on each operation of the machine in anti-clockwise direction and back in clockw1se direction. With this first-named motion the perforation 7 3 of the-check paper 74 is'efiected, as indicated in Fig. 11, between the two. impressions, while by said backward motion of knife 58 the check' is sheared off.

When no check is to be issued in an operation, the free edge of the check paper remains located on the level of knife edge 70 and punch 72. g

In contradistinction to the above-described mechanisms the means operating the roll 4 and the check feed mechanism are arranged so as to be shifted to modify the printing and check-feeding operations. These means cornprise two cam disks 75, 76, Figs. 2 and 3, causing a three times printing motion, .two cam disks 77, 78 causing a'single printing motion of roll 4, a pinion 79 and two locking disks 80, 81 for the checkfeed. These means are arranged on a drum 82, Figs. 2

and 3, connected to drive shaft 15 by splines 83 so as to be shiftable thereon. 'On its one end the drum 82 has a switch collar 84, Fig. 2, recessed at 85,the rear wall 86 of said recess being peaked. With said collar 84 cooperates 'an adjusting pin or lug 87 fixed on a bolt or rod 89 shiftable in the walls 34, 35 but secured. against rotation by a lock pin 88. A spring 90 normally keeps rod 89 in the inoperative position shown in Fig. 2 in which no check is issued. A knurled button 91 serves as a knob for pushing rod 89 against the action of spring 90 into operative posi tion causing a stub check to be issued, the lug 87 assuming then the position shown in .Fig. 2 in dotted lines. The button 91 is fixed for limited rotation on rod 89 and hasan arm 92 adapted to engage a lug 93 fixed to the wall 34 and thus to keep rod 89 in operative position. On its other end rod 89 carries a flange 94 under which engages an angle lever 95 pivoted on wall 35. A link 96, Figs. 2' and 4, connects the free armof lever 95 to a double lever 97 acted upon by a special key 98. selectin the line of business or the like of the machine. Upon depression of key 98,-rod89' is shifted into-operative position against the action of spring 90 and remains therein until the depressed key 98 is released. In the position of rest the recess 85 enables lug 87 to be pushed into operative position. As soon p as the. drive shaft 15 is set'in motion, then according to the position of rod 89 the upper or lower slope face of the peaked end 86, Fig. 2, of recess 85 strikes lug 87, whereby the drum 82 is shifted into operative or inoperative position at the beginning of the opnected by hub 3. Arm 100 has linked an a thrust-rod 102, Fig. 8, connected by an arm 103 of shaft '11 tofswing arms 105,106

one single printing motion to roll 4 during 1 the operation of the machine. With drum 82 inoperative position, however, the rolls 107, 108 co-operate with'the cam disks 7 6, 75, respectively, whereby three printing motions are imparted to roll 4 during theoperation of themachine;

The mechanismfeeding the check paper, Fig. 1, comprises a feed roller 109 and a companion roller 111 co-oper'ating therewith by its collar 110 which determines the length of the cheek. The-feed roller 109 has rigid on it a pinion 112 in mesh with a pinion 113 fast on'shaft 62. The latter has further rigid on it a pinion 114, Figs. 1, 2, three teeth of which, 156, 157, 158, are cut away for a cer tain part of its width. I

With drum $82 in operative position, the pinion 79 co-operates with the unmutilated portion of pinion 114 and the locking disk 80 with the mutilatedportion. pinion 79 are likewise mutilated and arranged in three groups, 159, 160, 161, so that a three step motion is imparted to pinion 114 upon shaft 15 rotating. The locking disk 80 has threecut away portions, 150, 151,152, and three full circumferential portions, 153, 154, 155. During the intervals between the individual steps of motion and in the position of rest of the machine the pinion 114 is lockedby the full circumferential portions of lockto ing disk 80 engaging the gaps of pinion 114 formed by. the cut away teeth 156, 157, 158. During the turning of pinion 114 its teeth are freed by the cut away portions of disk 80. The single revolution of shaft 15 causes the 415 feedroller 109 to execute likewise a single 1 full revolution which takes place, due to the described gear connection, in three stepsproducing what may be called a manifold or stepwise feed motion of thecheek paper. The

intervals formed by the stepwise motion of the check paper are filled by the perforating, printing and cuttin operation.

With drum 82 in inoperative position, pinion 114 is outof mesh with pinion 79, but in 58 mesh with looking disk 81 located beside disk 80. Said disk 81 has a full shell surface which projects into one ofthe gaps of pinion 114 so that, with the drum 82in inoperative position, this pinion'and therewith the feed roll- 6 ex 109 remain locked in their position of rest during the'operation of the machine.

The mode of co-operation of the described individual devices constituting the complete printing mechanism, is. as follows 68 Whenrod 89take's its inoperative position,

The teeth of Fig. 2, drum 82 is secured in inoperative positlon, at the beginning of the operation of the machine, by lug 87 or is broughtthere into if it had been set to operative position in the preceding operation. Now first the feed of the record strip, ink ribbon and consecutive number takes place by means of cam disks 16, 17, Fig,'6, and thereupon said single printing motion of roll 4 by means of cam isks 77, 78, this efiectin'g an impression to be made on the record strip.- As the date wheels 39 are b ein swung away by the curved groove 56, Fig. 5, during this printing motion, this impression on the record strip shows no date. During the operation the knife '58, Fig. 9, has imparted to it a turning motion, but. since the feed roller 109 remains locked, as pointed out above, no

feeding of the check strip towards the knife 58 occurs so that a perforation or severance of a check does not take place.

When rod 89 takes its operative position,

after being brought thereinto by means of button 91 or key 98, drum 82 is secured, at

' the beginning of the operation, in operative position by lug 87 or is brought thereinto if it had been set to inoperative position in the preceding operation.

The feed of the record strip, ink ribbon and consecutive number is then followed by the first step of motion of the check paper by means of pinion 79, and then by the erfora 'tion of the check by means of cam isks 68, 69, Fig. 7. About at the same time roll 4, coupled with cam disks 75, 76, executes its first printing motion effecting an impression on the record strip, the check paper, however still remains unimpressed, since it has not yet been fed up to the printing line. During this printing operation the date wheels 39 are being thrown out' so that the impression made on the record strip shows no date. The perforation is followed by the second step of motion ofthe checkpape'r and thereupon by the second printing motion of roll 4, the first impression (the upper in Fig. 11) thus bein 'made on the check. In the meantime the ate wheels had been thr'own'in, so that this impression contains the date, l ke the subsequent im resslon. When the third step of motion o the check paper -1s com-.

pleted, the roll 4 isrocked the.third time to make the second impression onthe check. Shortly after the operation 1s completed,

knife 58 is turned clockwise, thus shearing off the stub check from the paper and allowing itto glide out of the issue slot. I
